3 Claims.

This invention relates to new and useful improvements in closurefasteners such as may be used for doors on refrigerators, aeroplanes,automobiles and sundry other instances.

The principal object of the present invention is to provide a closurefastener which will be self-latching and in acting in this respect willserve to snugly hold a closure against any looseness that would tend topermit the escape of air, especially in instances where a door isconstructed for air tightness.

Another important object of the invention is to provide a closurefastener of the character stated which will be positive acting andsubstantially foolproof at all times.

Other objects and advantages of the invention will become apparent tothe reader of the following description.

In the drawings:

Figure 1 represents an outside fragmentary elevational view showing inbroken lines the position of the fastener and in full lines theoperating member therefor.

Figure 2 is a fragmentary sectional view taken on the line 2-2 of Figure1, but showing the fastener in closed position.

Figure 3 is a fragmentary sectional view taken substantially on the sameline as Figure 2, but showing the fastener in open position.

Figure 4 is a fragmentary detailed sectional view similar to that ofFigures 2 and 3 but showing the closure with the fastener being moved toopen position.

Figure 5 is a vertical sectional view through the fastener. V

Figure 6 is a horizontal fragmentary sectional view taken substantiallyon the line 66 of Figure 1.

Figure '7 is a fragmentary elevational View of the keeper.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 denotes a closure while numeral 6 representssome stationary structure such as a wall or the like.

Numeral I generally refers to the closure fastener which includes a box8 horizontally through which a bolt 9 of polygonal cross section isslidably disposed. On the bolt 9 is a collar I0 from which depends afinger II and located on the bolt 9 is a coiled compression spring I2which is interposed between one side wall of the box 8 and the collarII]. The spring I2 serves to urge the bolt to operated position as shownin Figure 2.

Numeral I3 denotes a shaft which extends through the closure 5 and isoperated by a handle I4. The shaft I3 at a point within the box 8carries a plate I5 which has a shoulder portion I6 adapted to abut thefinger II. A spring I! convoluted on the shaft I3 and having one endbearing against the box 8 and the other against the shoulder I6 servesto maintain the shaft I3 and the handle I4 in substantially the positionshown in Figures 1 and 2. A stop I8 is provided in the box 8 for theplate I5. a

The bolt 9 slides through a bracket structure I9 vertically throughwhich is disposed a shaft 20 having a crank 2| at its upper end, thiscrank being engageable against a strip spring 22 suitably secured to theback wall of the box 8. An L-shaped detent 23 is carried by the shaft 20and has a lug 24 at one end thereof engaged with a recess 25 of the bolt9. The other end of the rockable detent is engageable by the head of apin 26 which is slidably disposed through a guide 21 at one side of thebox 8.

A channeled flapper 28 receives one end of the bolt 9 and is pivotallysecured thereto as at 29. The pin 26 extends into the fiaper 28 andengages the same as substantially shown in Figure 3.

An inclined keeper 3!! having a roller 3I at its low point serves as awedge against which the flapper 28 can act in wedging the closure 5 to asnug closed position.

It can be seen that when the handle I4 is pushed downwardly, theshoulder IE will act against the finger II and force the bolt 9 to theright in Figures 2 and 5, to the position substantially shown in Figure3, until such time as the recess 25 reaches the lug 24 of the detent 23whereupon the spring 22 will act on the crank 2I and move the lug 24into the recess. The door 5 can now be pulled open and the handle I4released. The parts will remain in the position shown in Figure 4.

When the door 5 is closed, the flapper 28 will ride against the roller3I, forcing the pin 26 inwardly and rocking the detent 23, so that justas the flapper substantially passes the roller 3|, the lug 24 will beremoved from the recess 25, thus freeing the bolt 9 so that the springI2 throws the bolt and flapper 28 to the left as shown in Figure 2.

The flapper 28 will ride the slope of the keeper 3Iland this wedgingaction will draw the door 5 snugly against the jamb.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to Without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, What is claimed as new is:

1. A closure fastener comprising a stationary keeper having an inclinedportion, a movable closure, a spring projected bolt on the closure,manual means for retracting the bolt, said bolt being provided with apivotal rider at one end thereof for riding the slope of the keeper, anddetent means for the bolt, said detent means comprising a rockablemember adapted to hold the bolt in retracted position, and a slide pinoperated by the rider at its retracted position for tripping the detentmember.

2. A closure fastener comprising a stationary keeper having an inclinedportion, a movable closure, a spring projected bolt on the closure,

manual means for retracting the bolt, said bolt 20 being provided with apivotal rider at one end thereof for riding the slope of the keeper, anddetent means for the bolt, said detent means comprisin a rockable memberadapted to hold the bolt in retracted position, and a slide pin operatedby the rider at its retracted position for tripping the detent member,said detent member being provided with a crank and a spring acting onthe crank to move the detent to holding position with respect to thebolt.

.3. A closure fastener comprising a stationary keeper having an inclinedportion, a movable closure, a bolt on the closure having projecting andretracting means, said bolt being provided with a pivotal rider at oneend thereof for riding the slope of the keeper, detent means for thebolt, said detent means comprising a rockable member adapted to hold thebolt in one position, and a slide pin operated by the rider for trippingthe detent member.
